False Oaths

Hadith is about False Oaths :
Reported by Abu Umamah Iyas bin Tha’labah Al-Harithi (RA): The Messenger_of_Allah (peace be upon him) said, “He who misappropriates the right of a Muslim by taking a false oath, Allah will condemn him to the fire of Hell and will forbid Jannah for him.” A person asked: “O Messenger of Allah, even if it is something insignificant?” He replied, “Yes, even if it is the twig of the Arak tree.” (#Muslim)
